Ceilometer CL51 raw data measured during POLARSTERN cruise PS122/2, links to files

The meteorological observatory Polarstern continuously operates a ceilometer to measure cloud height and vertical visibility. The instrument features an upward pointing pulsed diode laser centered at a wavelength of 910nm. Using Light Detection and Ranging (LIDAR) technology the instrument records the backscatter, predominantly caused by hydrometeors such as precipitation and cloud particles. Measurements are taken approximately every 36 seconds. All data published here is left "as recorded", no quality control was applied.

北极星号（Polarstern）气象观测站持续运行一台云高仪（ceilometer），用于测量云高与垂直能见度。该仪器搭载一台朝上发射的脉冲二极管激光器，中心波长为910纳米。仪器借助激光雷达（Light Detection and Ranging，LIDAR）技术记录后向散射信号，此类信号主要由降水、云粒子等水成物粒子产生。测量间隔约为每36秒一次。本页面发布的所有数据均按原始记录直接留存，未进行任何质量控制操作。
